"DRAW-BAR EXTENSION.

Patented Juiy 30,1907.

To all whom it may concern:

Be it known that I, HERMANO. PRIEBE, a citizen oi the United States, residing at Blue Island, county ot Cook, and State of Illinois, have invented certain new and useful'f'lmprovements in Draw-Bar Extensions, oi which the following, taken in connection with the drawing, is a description. ggf

My invention has for its object the production of an improvement in draw bars, more particularly with that part oi the construction which coperates with the (irait rigging, and is designed to be used upon railway cars in combination with different forms of draft rigging.

, In this instance my invention resides more particularly in the draw bar extension shown vin the accompanying drawing. The novel features and advantages of my invention will be hereinafter pointed 'out in the following descripltion. i

ln the accompanying drawings, in which` I have used like lettersofreference to indicate like or correspending paris, l have illustrated what l nowconsider the preferred form of my invention and in these drawings Figure 1 is a side elevation of my invention; Fig. 2 is a top plan view'of the same, partly in section and illustrating the use of the coiled compression springs; Fig. 3 illustates a top plan view of iny draw bar exten.. sion with transverse leaf compression springs; Fig. 4 is a side elevation of- Fig. 3, with the follower bars re moved, and Fig. 5 is a sectional'rview taken on line 5-5 of Fig. 4. Fig. 6 .is a plan view of the resistance plate disposed between the draw bar and the trans tion having at the rear thereof the shoulder a.

.and supports the compression A are the draft sills upon each side oi the cir, one side only being shown for the purpose of illustration. I

Rigidly secured to the tail of the draw bar is an extension B, said extensitn B having a web b between the top and bottom thereofthroughout the greater portion of its length. This web is provided with an elon.` gated opening c through which is extended the follower` bars C, C. The extcnsioiA B is provided with shoulders c whichta'ke over the shoulders a on the tail ofthe draw bar. As illustrated in Fig. 1 I have provided a Vstrengthening strip b upon the top and bottom oi the b in the oxtonsionl.: `A spring seat c3 which. is slotted at each end thereof rests upon each of the follower bars springs in proper position. y

Aextension B and hooks over the shoulders cf. ln this 'which` plate vreceives the impact of the springs on the f I of against the follower C and in operation receives the mentioned and transmits the saine action to the springs ward extension rigidly secured thereto, and a web formed In' Figs. 3 and 4 Ihaveillustrated the use of leaf springs in combination withJny draw bar extension, also a reinforcing strip D which entirely surrounds the instance lugs or projections d d/ lare provided between the upper and lower portions of the extension B between which projections are a plurality of transverse springs e, af, disposed parallel with the follower bars C, C. Y-

As shown in Fig. 3 the springs e are straight and the springs eareconcave, and are so assembled that they alternate with each other. A plate 'e2 is disposed between the projections d and the transverse springs, '4

forward pull; the rear plate e rests upon each end thereimpact of the builing strain. It will be observed that at all times the strain it distributed at theithree points upon either the buffing or pulling strain. y In the drawings I have illustrated my invention used with either transverse leaf springs or twin coil springs,

but Wish to be understood as contemplating also the.

use of outside compression springs, such for instance as are illustrated inmy Patents Nos. 747,637; 799,262

`and 799,263.v

I claim: 1. In a device oi the class described, the combination of the underframing of a. car, n draw bar having a rearward extension rigidly secured thereto, and an elongated web formed integrallywith said-extension.

.2. In a device of the ciasdescribed, the combination, of the underframing of a caff-a drnw bar having. ay rear- 9 integrally with said extension, said web having an elonl gated opening thereth'rough.A v

3. In s device of the class described, the combination of` the draft sills of a cnr, a draw bar movable between said sills, 'an extension rigidly secured .to and made a part of v95 sniddrawban a'web formed Jintegrally with the top and bottom of said extension, said web yhaving an elongated slot therethroughcoincident elongated slots througli'tlie 'aforesaid draft sills, follower bars extending 'through said slots, and a plurality of cushioning springs between said follower bars.

4'. In a device of the class described, the combination of the draft sillsof a carpa draw bnr movable between said sills, au extensionl rigidly secured to and made a part of said draw bar, projections extending inyardly from the top and vbottom of saidv extension, followei' bars extending through said extension and through the aforesaid drnftm'k f sills, and transversesprings disposed between said follower liars inside of the draft sills. l

5. In a device of the class described, the combination 11() of the nnderframing of a car, a draw bar movable therein, rin extension rigidly secured to said draw bar, oppositeiy extending projections upon the inside of said extensionfollowei bars extending through said extension and be? tween the aforesaid projections, and leaf springs disposed 1] 5 between saidfollowerbars and parallel therewith,

6. In a device of the class described, n drangbar, an extension rigidly secured to said draw bar', ppositely said follower bars and a resistanceplate between the? forward follower and said springs.

7. In a device of` the class described, the combination of the drnw bnr, u re'arwnrd extension, n strengthenim z strip sin-roundings'nid extension, said strip und the reni ward extensionI rigidly secured to the draw bur. integral projections upon the inside of said extension follower bnrs extending through said extension between the ,aforesaid l() projections :ind alternate straight and concave ,springs be, tween :1nd parallel with said follower bnrs.

In testimony whereof, I have signed lthis specification in the presence of two Subscribing witnesses.
